Generator Transfer Switch Wiring Configuration

Application: Installing a Generator Transfer Switch.
Skill Level: Advanced. This electrical wiring project is best performed by a Licensed Electrical Contractor or Certified Electrician.
Tools Required: Electricians pouch of hand tools and the various power tools necessary for installing the generator and transfer switch.
Estimated Time: Depends on the type and size of the generator and transfer switch and the available access to the project area.
Precaution: Any existing electrical wiring within the immediate area that may interfere with the installation of the generator transfer switch may need to be relocated if necessary.
Important: Installing a generator and transfer switch must be well thought out and performed with a permit with all of the work being inspected.

The Importance of Proper Wiring Configuration and Isolation

The Basic Wiring Configuration for a Typical Generator Transfer Switch:

Each Wiring Termination must be correct for the Power Conductors of the Line or Load.
Neutral conductors are attached to the Neutral Terminal Block.
All enclosures and equipment must be grounded and bonded.
NOTE: Some transfer switches may have the provision for transferring the Neutral Conductors.

Alternatives to a Generator Transfer Switches

IMPORTANT: All generator transfer switches and generator panels should be installed by a licensed electrician and all the work must be inspected.

Portable Generators for Immediate Emergency Power

Portable generators are great for powering up a few devices by using appropriately sized extension cords without connecting to the home electrical system. Refer to the Operating Manual which comes with the Portable Generator for specific details and Safe Operation.

  1. Dave Rongey says:

    Michael,
    The location of the transfer switch would depend on the circuits that will be provided with generator power during an outage.
    Will the generator be large enough to handle the total load, or just the circuits located at one panel?
    Dave

  2. Michael says:

    If one has a 400 amp service that is split between multiple load centers, how is the transfer switch to be wired?

  3. Dave Rongey says:

    Hi Arnold,
    The size and amperage of the electrical components that will be installed for a generator system are determined by the size of the generator, and the electrical circuits that will be placed on generator power.

    I hope this helps,
    Dave

  4. Dave Rongey says:

    Hi Arnold,
    The wiring for a 6 circuit transfer switch will depend on the specific setup at your location, and the type of transfer switch or generator panel that you get.

    I hope this helps,
    Dave

  5. Arnold Strzelecki says:

    Do you need a 50 amp for the switch?

  6. Arnold Strzelecki says:

    I need a book or instructions about how to wire a 6 circuit transfer switch. Most electrical books do not have that info. Just basic electrical wiring.
